Application J une 7 Claims.

This invention relates to detachable connections and more particularlyto bed post attaching means, although it may be employed with equaladvantage for other purposes.

It contemplates more especially the provision of means for enabling theready association and disassociation of complemental members to effect arigid detachable joinder therebetween.

Numerous devices have heretofore been proposed for effecting the readyassociation and disassociation of complemental units, but these have notproved entirely satisfactory in that they are expensive, and notentirely effective in assembling complementary members with facility;therefore much inconvenience and labor is entailed in the use thereof.

Further, it is exceedingly desirable to provide means for effecting ajoinder of complemental members in reversible positions so as to enablethe disposition thereof in variable relation with facility.

One object of the present invention is the provision of novel means foreffecting the rigid association or disassociation of complementalelements.

Another object is the provision of slidable cooperating means to effectthe ready association and disassociation of members.

A further object is to provide simple and inexpensive means for enablingthe detachable connection of members disposed in rigid relation to eachother.

A still further object is to provide means capable of variableco-operation to enable reversible connection therebetween.

Still a further object is to provide means to effect a rigid joinderbetween complemental members of a bed to enable convenient assemblythereof.

Other objects and advantages will appear from the following descriptionof an illustrated embodiment of the present invention.

In the drawing:

engaging means employed in association with a member; and

Figure 6 is a View in elevation of means capable of co-action with themeans disclosed in Figure 5 to effect a rigid joinder betweencomplemental members.

The structure selected for illustration is shown in association withcomplemental members constituting component parts of a bed frame;however, it may be employed with equal advantage for effecting a rigidjoinder between other members.

The complementa-1 members comprise, in this instance, a bed post 1()-consisting of the usual metallic tube preferably though not essentiallyof rectangular configuration. To enable a rigid joinder of the bed post10 with parallel disposed bars 11 disposed between the end faces of thebed to constitute the spring support, a plate 12 is riveted or otherwise10 by virtue of its angularly related shank 13 which has an arcuatedepression 14 co-actable with the exterior of a round post asdistinguished from the flat surface with which it is shown to contact. Amember 15 is disposed within the post l0 to receive fasteners such asthe rivets 16 therethrough, thereby permanently affixing the plate 12 tothe post 10.

It is to be noted that the member 15 has arcuate surface 17 circle sothat it can be reversed to contact with a circular surface of a roundpost. This arrangement enables the attachment of the plate 12 to eithera fiat or arcuate surface which are interchangeably used in'themanufacture of beds. 9

As shown, the member 12 projects from the face of the bed post 10 andterminates in an arcuate edge 18 which is shaped to define a hook 19 incommunication with a vertically disposed slot 15 communicating with anedge thereof. Obviously the slot 20 may be provided in the plate 12 inany suitable position it preferably extending in a vertical direction toreceive a member complemental thereto to effect a rigid joinder betweenfixed to the bed posts constituting a segment of a the angle bars 11arranged to maintain a bed 100 spring thereon.

To enable the ready association and disassociation of the bars 11 withrespect to the bed post 10, means capable of cooperation with the slot20 are aflixed thereto. The cooperating means consist in this instanceof an elliptical plate 22 having one edge 23 thereof substantiallystraight to coact with a correspondingly shaped edge of the slot 20. Theother edge 24 thereof tapers toward 110 a midpoint 25 which is removedsufficiently from the edge 23 to permit the disposition Vof the plate 22Within the slot 20. It is to be noted that the tapering edges 24facilitate the reception of the plate 22 Within the slot 20 in eitherdirection, the portion 25 contacting withV the edge of the slot 20 inoperative position to insure a rigid connection therebetween Withoutpermissive lateral movement.

Accidental removal of the plate 22 from the slot 20 is prevented byassociating a plurality of discs 26, in this instance three, with theplate 22 in any appropriate manner so that portions thereof will projectbeyond the edges of the plate 22 to insure the guided dispositionthereof Within the slot in only a vertical direction, the projectingperipheral edges 27 of the discs 26 being spaced from the face of thebars 11 by the plate 22 to form a guideway therebetween to receive theslotted plate 12.

The discs 26 consist in this instance of a plurality of circular plateshaving reduced shanks 28 which project through suitable apertures in theplate i7 and bars 11 so that the extremities thereof may be flattened asat 29 to maintain the discs 26 and plate 22 xed to the bars 11. Thecircular discs 26 are preferably disposed in alternate relation so thatthe portions thereof projecting over the plate 22 dene a guide on boththe edges 23 and 24, the latter edge being provided with a circular disc26 at the point 25 dened by the angularly related portions thereof. Theother discs 26 overlap the edge 23 near the extremities of the plate 22to slidably guide the complemental members 10 and 11 to a positioneffecting a rigid joinder therebetween. It

is to be noted that the plate 22 having the discs 26 fixed thereto todene projecting' flanges 27 can be introduced Within the slot 20 fromeither end thereof, thereby enabling the bars l1 which preferably are ofangular cross-section to be reversed. This arrangement is veryadvantageous in bed constructions, not only because it affords thedisposition of bed springs 30 thereon at various altitudes, but alsoeffects the connement thereof Within predetermined limits dened by thevertical flange 31 of the angle bar 11. (Fig. 1.)

It will be apparent that novel means have been provided to enable theready association and disassociation of Vcomplemental members so thatthey may be assembled with ease and Without entailing much labor andexpense.

Various changes may be made in the embodiment of the invention hereinspecifically described Without departing from or sacricing anyadvantages thereorn as dened in the appended claims.

We claim:

1. Complemental members, one having a slot therein, the other memberhaving a plate affixed thereto for introduction into said slot, saidplate being shaped to enable the reception thereof into said iirstmember in reversed positions, and discs alternately spaced on said plateto extend over the edges thereof to dene a guide- Way for said slottedmember.

2. Complemental members, one comprising a slotted plate, the secondcomprising a plate shaped to substantially correspond with the slot insaid first member, and a plurality of discs afiiXed to said second platein projecting relation for coaction with said slotted plate to denne aguideway therefor.
